摘要：In a method of drying a moist bulk material, such as sewage sludge, andtreating the malodorous moisture-laden gas resulting from the drying process, themoisture-laden gas is introduced into waste water contained in a waste water clarifyingbasin of a waste water treatment plant. A system for carrying out the method includes adrying apparatus and at least one waste water basin of a waste water treatment plant,connected so that the moisture-laden gas emitted from the drying apparatus can beintroduced, for example through an aerator, into the waste water. Thereby, the gas iscooled, demoisturized and deodorized, and moisture and volatile components arecondensed and/or dissolved out of the gas into the waste water. The waste water isbeneficially oxygenated, heated, and enriched with organic substances.
